Application filed June 8, 1918;eria1fio. 771,567.' Renewed mm; 12, 1918. Serial No. 103,846.

To all whom it may concern:

Be it known that I, HENRY REIqHnN- nncn, a citizen of the United States, residing at Rochester, in the county of Monroe and.

5 State of New York, have invented certain new and useful Improvements in Carbureters; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. v i

' My invention relates to improvements in carbureters,-and it consists in the constructions, combinations and arrangements herein described and claimed. An object of my invention is to provide an improved 'carbureter adapted to produce an efiicient mixture under all service conditions and to. operate advantageously with either light or heavy fuel oils.

A further object of my invention is to providea compact. and strong carburetor which will operate with certainty a -high fuel economy. 26 .s-z-In the accompanying drawings,'forming a part of this application and in which similar reference symbols indicate corresponding parts in the several views -Figural is asideeIeyation illustrating 80 one embodiment of my invention;

,Fig. 2" is a plan of he construction shown inF1g. 1; i

" 3 is a vertical section on the line 3 -3 0 g; 2; Fig. 4 is an enlarged section on the line 1- loi.li3ig.2; Fig. 5 is an enlarged horizontal section on. theline 5-6 of Fig. 3;

be secured to the intake of an internahcombustion engine in any suitable manner, as by.

o'ckingly engage any desirednotch of which one isshown-oi a spaced-series on the spindle {3- of, an inlet valve 7, for adjusting theposition of said float to vary the liquid, level maintained thereby in said tank 3.

Referring to the drawingsl indicatcsan open ended rectangular conduit adapted to wall of the conduit 1 and telescope snugly over the feed tubes 11; the u er ends of said sleeves bein secured to a s lftable plate 14 and provide with air admission apertures 15. The lower ends'of said -sleeves 13 -are.provided with diametrical plates 16 constituting thin webs for fitting within the feed slots 12 to control said slots u on shifting of said sleeves 13; said shifta le plates 16 acting effectively to clean'the feed slots 12 for greventing the troublesome clogging whic has prevented the employment of efficiently narrow fuel feed slots in previous constructions. Cores 17 are secured concentrically on said ,Webs to prevent the indrawn current of air from depressing the fuel in the tubes 11.

By making the slots 12 rectangular in Patented Apr. 17, 1917.

outline, I am enabled to establish easily a relationof diiferential proportioning between the effective opening of said slots and-the efi?ective divergence between the deflecting plates, by varying one dimension only. I

cause the slots-to become longer or shorter as the opening between the deflecting plates becomes wider or narrower. The rectangu-- lar shape of the'conduit is of important consideration at this point, because this con structlon makes possible the use of rectangulan'straight edged plates as the sole controlling or constricting means for the effective air-opening or-passageway; I am thus ention of the curve of cam 19-, a matter of comparative simplicity. v

The-tank 3 is shownelamped tot-he conebled to establish 'lny difierential curve in one plane, thus mak ng the plotting ofsuch curve and the corresponding construcloo duit 1 by a band 8 and connected to the fuel chamber 9 by a curve d or otherwisesuitably shaped, pipe lflgsaid curved pipe providing a sufliciently yielding connection to permit shifting of the tank 3 to difierfent positions within its clamping'ring 8 for readily -varying the level of the fuel in saidtank to regulate-the fuel level in the feedtub'esl'l.

'Asshown in the drawings, the inlet tank 3. is connected with'a suitable source of fuel siipply aninlet pipe lg-11inch is formed,"

I of flexib e material, or otherwise constructed to permit adjustment of said tank within said tubes 11. The rectan'gula'riconduit 1 is its clamping band 8.

A cam 19 is secured on a spindle 20 in position for actuating the shiftable plate 14 carrying the telrmcoping sleeves 13; said cam being formed to elevate the plate 14 with a progressively augmented action. As shown especially in Fig. 2, the spindle 20 is jour-' nuled in bearings on a slotted plate 21 adjustably secured on the conduit- 1 by screws 22, for shifting said spindle to vary the position of the cam relative tothe plate 1 4 and thereby govern the effectiveness of the fuel openings. A sprin engages thqshiftable plate 14 for yie dingli maintaining the latter in contact with t e cam 19; said spring tending to hold the telescoping sleeves 13 depressed to close the fuel feed slots 12. J a

The shape of this 08111 15 made in 1accprdance with the differential curv'e' determined through trial, of the completely effective relation between the varying positions of the diverging deflectors or constricting plates and the width of the fuel feed slots deter mined by positions of the sleeves 13. Therefore, the position of the cam, which is determined by the position of the constricting throttle plates, which in turn is determine by the pull or suction of the engine, determines the differentially proportioned position of greatest efiiciency, of the fuel supply controlling sleeves l3.

The spindle '20 is provided with a crank 23 having a series of perforations 24 for adjustable connection to a link 25 piyotally connected to a slide 26, on the conduit 1. The slide 26 is yieldingly maintained in its normal position by a spring 36, and is connected by links 27 to cranks 28 and 29 secured to shafts 30 and 31, respectively. A pair of rectangular deflectors 33 and 34 are secured on said shafts 30 and 31; said deflectors closely fitting within the rectangular conduit 1 and being yieldingly held with their free ends in contact by the spring 36 to normally close said conduit. :As shown especially in Figs. 3 and 5, the free ends of the deflectors are bent, or ofiset, and provided with slots for receiving the fuel tubes 11 and sleeves 13; said deflectors 00- operating. with the walls of the conduit 1 to provide a rectanghlar converging nozzle for directing the indrawn air in ajet direetly across the rectangular feed slots 12 of shown provided with a cylindrical intake end 37, in which is mounted othrottle valve- 88 having a crank 39 for connection to any usual governor, or manually-operated mechanism. The nebulizin part of the carbureter is thus located ietween the throttle and the engine, so that by means of the throttle, the nebulizing elements may be maintained in completely controlled relation to the engine suction, as well as kept during idleness from the contaminating dust of outside air as well as va r l I In the operation 0 my invention, the deflectors 33 and 34 are swung apart by the engine suction to provide a rectangular conduit for directing the indrawn air n a et directly across the rectangular fuel-feed slots 12 the actuation of said deflectors beg proportionate to the degree ofrthe engine suction, and the'relation between the effective areas of the rectangular air-'admiasion nozzle and the rectangular fuel-feed slots, being maintained un er all service 5 conditions. j

By this constructi the indrawn jet of air acts effectively to raw in and to finely atomize or nebulize the fuel fed through the slots 12; thereby insuring an eflicient' and satisfactory mixture under all various operativeconditions.

It is to be noted that the walls of the fuel feed openings are straight and perpendicular to the direction of the air current or feed blast. The blast is thus directly across the narrow slot or feed opening. Greater nebulizing efliciency is thus obtained. When the blast is along or parallel with a metallic surface, the iguid, fuel is likely to creep along said sur aoe either with or-against the last. As it does so, it'loses its more volatile constituents, and the heavier hydrocarbons left accumulate until they are taken 01! by the air current in the'form of dro s or blobs of considerable size. These rops when carried into the explosion cylinder, are oxidized only partially or not at all, and are carried by the exhaust into the atmosphere and waeted- I remedy this by lead ing a narrow efl'ective blast st aight across the straightwalled narrow slo 12. It ma be called a shearing blast, and all the para fins or other hydrocarbonsof the fuel are caught up at once and blown ofl' in a nebula of finely atomized dr (1'. e. free from drops), spray, and in a con ition of maximum sublVlSlOl'l. g I

From the above description, it will be understood that my improved construction provides adjustable means for regulating the proportions of the air and fuel and the governing operation of the several parts; thereby a opting it for efiicient use under all ractical conditions and with both lightand 120 have illustrated an satis acto constructio but cha could be-made v vithin the spii i t and acop is df my invention. p 12s I claim 1.
